Features
Type
FZL 4146 G
General Description
The IC comprises four driver circuits capable of driving power transistors (PNP or
PMOS). The output transistors are protected against short-circuit to ground and supply
voltage. The turn-ON threshold can be set from 1.5 V to 7 V. Overload at one or several
outputs will be indicated at pin SQ (signaling output). The corresponding power
transistors are then protected by changeover to clock-governed operation.
Circuit Description
Each driver circuit has one active high driver input Dl and a common enable input ENA
(active high) is provided for all stages. The Q output is designed to drive the output
transistors. The load current is sampled and, if necessary, limited via pin W. If the load
current exceeds the preset value, the output stage switches off. Switching-ON again is
provided by the built-in clock generator T. Its operation requires an external capacitor
at pin CE. If
operating this key. The duty cycle of the clock generator is 1:47 (e.g. 45 s/2.1 ms with
C
When the supply is connected, the internal RS-FF goes into the state corresponding to
the released output.
